Abstract

"PNEU DE ALTO DESEMPENHO PARA UM VEìCULO MOTORIZADO, E, PROCESSO PARA PROMOVER UMA DISTRIBUIçãO UNIFORME DE UM COMPOSTO DE BANDA DE RODAGEM DE UM PNEU DURANTE VULCANIZAçãO EM UM MOLDE APROPRIADO". Um pneu de alto desempenho (1, 51) para um veículo motorizado é dotado de uma banda de rodagem (2, 52) que compreende duas ranhuras circunferenciais profundas (3, 6, 53, 56) que separam uma região central (7, 57) de duas regiões de ressalto laterais (8, 9, 58, 59) dotadas de blocos de ressalto (20, 120, 64, 164); na banda de rodagem (2, 52) a soma das larguras das regiões de ressalto (8, 9, 58, 59) é igual a ou menor do que 60% de sua largura total L, a largura de cada região de ressalto (8, 9, 58, 59) não é menor do que 20% da largura total L, em que cada uma de ditas ranhuras circunferenciais (3, 6, 53, 56) é adjacente, sobre o lado além de dita região central (5, 57) a uma trilha contínua (22, 122, 66, 166) a partir da qual são ramificadas ranhuras transversais (21, 121, 65, 165) que delimitam os blocos de ressalto (20, 120, 64, 164)."HIGH PERFORMANCE TIRE FOR A MOTORIZED VEHICLE, AND, PROCESS TO PROMOTE UNIFORM DISTRIBUTION OF A TIRING COMPOUND OF A TIRE DURING VULCANIZATION IN AN APPROPRIATE TEMPLATE". A high-performance tire (1, 51) for a motor vehicle is equipped with a tread (2, 52) which comprises two deep circumferential grooves (3, 6, 53, 56) that separate a central region (7, 57 ) of two lateral shoulder regions (8, 9, 58, 59) provided with shoulder blocks (20, 120, 64, 164); in the tread (2, 52) the sum of the widths of the shoulder regions (8, 9, 58, 59) is equal to or less than 60% of its total width L, the width of each shoulder region (8 , 9, 58, 59) is not less than 20% of the total width L, where each of said circumferential grooves (3, 6, 53, 56) is adjacent, on the side beyond said central region (5, 57) to a continuous track (22, 122, 66, 166) from which transverse grooves (21, 121, 65, 165) are bounded that delimit the shoulder blocks (20, 120, 64, 164).
